I lost my best friend of the past fifteen years. As an only child, this guy was the closest thing to a brother that I ever had. He was an outstanding artist and a phenomenal human being. He died of a sudden kidney infection which ultimately became kidney failure. He was 33.
Due to financial difficulties, he didn't see a doctor as often as he should, and, even once he started to experience some symptoms (intense back pain, etc.) he waited a few days before going into the hospital -- likely because of the anticipated cost of an ambulance, hospital stay, etc.
I know some of the blame rests on his decisions, but I cannot help but feel as though America's shitty healthcare policies and outrageous costs have kept many people from seeking proper medical assistance until it was too late.
So please, regardless of the cost, please seek medical attention if you require it.
